Title: Improvements relating to valves or cut off devices for gas stoves and similar services
Filed: 1922-01-24
Abstract: 195,804. Walton, H. Jan. 24, 1922. Fluid-actuated valves with thermal control.-A valve for cutting off the supply of gas to a heating device is operated by one or more diaphragms which is or are controlled bv the gas pressure and by a device responsive to the temperature of the heating device. The valve f, Fig. 1, controlling the supply of gas from the inlet passage g is mounted on a spindle h, carrying two diaphragms c, e. The chamber d is placed in communication with an air chamber subjected to the temperature of the heating device, so that the air pressure tends to open the valve against the action of the spring j and the diaphragm c. If the gas flame is extinguished, the reduction of pressure in the chamber d allows the valve to close. The valve must be held open bv hand until the required temperature is established. In a modification, Fig. 2, a single diaphragm e is open to the gas pressure in the chamber b, and to the pressure due to the heated air chamber in the chamber d. A quick closure of the valve f is ensured by providing a release valve l which allows the air in the chamber d to escape as soon as the closing movement commences.

IPC: G01V3/24
Filed: 1959-01-26
Abstract: 928,583. Geophysical surveying. BRITISH PETROLEUM CO. Ltd. March 15, 1960 [Jan. 26, 1959], No. 2728/59. Class 37. In a well logging arrangement for a borehole containing a conducting fluid, a substantial portion (more than one third) of the borehole wall is scanned by measuring successively and cyclically the currents to each of a group of electrodes disposed around the sonde periphery in a horizontal plane or by a rotating single electrode, the variations in current intensity being recorded. Square electrodes 12, Fig. 2, are mounted with their diagonals vertical and horizontal in, but insulated from, a guard electrode 10 and produce a narrow focused electric current beam. A transformer 21, Fig. 4, provides L.T. and H.T. power for the sub-surface equipment, and the guard electrode is fed via a current stabilizer 20, a rotary switch 22 connecting each electrode in turn to the guard electrode through the primary winding of a transformer 23, and the rest directly to the guard electrode. The value of the electrode current may be conveyed to modulate the intensity of a cathode-ray beam by a telemetering device 27 which may effect frequency transposition to return the signal to the surface over the same cable. The time base of the oscilloscope is synchronized with the rotary switch and the trace is photographed on a film which is moved across the trace in step with the vertical movement of the sonde in the borehole. The apparatus may be used in conjunction with the inclinometer described in Specification 838,061 the North pulse of which may be used to trigger the oscilloscope timebase. The signals may be stored in a magnetic drum for subsequent read out, may be used to make a plot on sensitized paper or may be conveyed to separate indicators corresponding to the electrodes for photographing. A number of layers of electrodes, or a number of longitudinally spaced electrodes may alternatively be used, the display arrangements being modified accordingly. Arrangements for improving beam focusing are discussed. Dimensions of the sonde are included in the Specification. Specification 833,990 also is referred to.
